 You need to set the property _DT_WORKSPACE_PRESENCE on the toplevel in
 question to the list of X atoms that describe the workspaces you want
 to put the window on.  The format of the property is a collection of
 32-bit atoms, and the type should be _DT_WORKSPACE_PRESENCE.  You can
 query the settings using the following piece of cryptic code...

    xprop -f _DT_WORKSPACE_PRESENCE 32a _DT_WORKSPACE_PRESENCE

 Setting the property is not possible directly in Tk; you will need to
 use a little extension.  You will also need to be aware that Tk wraps
 every toplevel itself with an extra window which it uses to implement
 menu bars.  Workspace names are of the form ws[0-9]* before internment.

 Be very careful when messing around with X properties; you can cause a
 lot of damage!
